I know I am smelling coolant when I park in the garage but I see no leak anywhere. I know I read about this somewhere but can't find it.

Is this a thing?

 

I've smelled it on every vehicle I've owned including my 2022 110 P400.

 

I've been noticing this as well on my 22 110 P300. I've been keeping an eye on the coolant reservoir, and it hasn't been dropping. Very puzzling, no idea how this could be considered normal. I only notice it sporadically, maybe it's linked to longer trips (>20 mins) but not sure

 

I had a similar issue and was looking under the hood and checking hoses, turned out to be one of the auxiliary radiators slowly leaking when under pressure, P300 as well. Found it when the wheel well liner was off since it was on the backside of the radiator. Replaced under warranty. Hope this helps!

 

I've got the exact same thing, '21 p300 110.

 

That looks major enough to leave evidence on the garage floor. Was that the case?

 

Thankfully it was actually a pretty slow leak. For a couple months before I took it in for a fix I was adding about ~1.5 cups of coolant mix per month.
